Common Orthopedic Tests

St. Joseph’s Westgate offers a full range of orthopedic diagnostic services.


When standard X-rays don't show enough detail, your orthopedic surgeon may use arthrographic images, which are a more thorough type of X-ray. Arthrography uses a series of X-rays enhanced by a contrast material that is injected into your joint, which is then viewed using a special piece of equipment called a fluoroscope. Arthography is most often used to look at shoulders and knees, but can be used on most joints.

Computed Tomography (CT)

A CT scan uses a combination of X-rays and computer technology to create images of structures inside your body using a series of cross-sectioned pictures. During this orthopedic test, you will lie on a table positioned inside a large doughnut-shaped machine. The CT scanner will send the X-ray beam through the area being studied in multiple positions. Surgeons review the images individually and as a group determine the best course of treatment for you.


Ultrasound is often used with other orthopedic tests to provide an additional view of the joint. An ultrasound uses high-frequency sound waves to look at joints and other structures inside the body. During an ultrasound test, a doctor or technician will use a device called a transducer over the part of your body being studied. The transducer sends sound waves, which bounce off the tissues inside the body. The transducer catches the waves that bounce back, and images are created from these sound waves.
